Patent GB-999361-A (GB)
Title: Improved method of producing fuel cell electrodes and the electrodes produced thereby
IPC: H01M4/98
Filed: 1962-05-04
Abstract: Sintered porous electrodes are made from a powder mixture of a catalytically active metal such as Fe, Ni, Co, Mo, W, Ag and an alkali soluble metal or metalloid such as Al, Mg, Zn or Si, the compacted mixture being sintered at 10-150 DEG C. below the melting point of the lower melting constituent and the major part of the alkali soluble constituent is then leached with an alkali.  The powder mixture should contain at least 50% by weight of the active metal, 10-30% of the alkali soluble metal and optionally 30% of ammonium carbonate or bicarbonate as a pore former.  Several examples of the process are given quoting powder particle sizes, pressures and temperatures.

Title: Process for the production of 3-chloro-4-hydroxytetrahydrofuran
Inventor: HAWKINS EDWIN GEORGE EDWARD
IPC: C07D307/20
Filed: 1957-05-31
Abstract: The adipic acid ester of mixed geometric isomers of 3-chloro-4-hydroxytetrahydrofuran is compatible with polyvinyl chloride and is a good plasticizer therefor in all proportions.ALSO:3-Chloro-4-hydroxytetrahydrofuran is prepared by heating 1 : 2-dichloro-3 : 4-dihydroxybutane under neutral or acid conditions whereby hydrogen chloride is eliminated between the terminal hydroxy and chloro groups.  The low boiling isomer of the product, B.P. 87-90 DEG  C. at 15 mm. Hg., is novel.  The 1 : 3-dichloro-3 : 4-dihydroxybutane may be present in the reaction mixture as such or may be formed in situ, e.g. from the mono- or di-esters with carboxylic acids such as acetic or formic acids by hydrolysis or by alcoholysis in the presence of p-toluene sulphonic acid or sulphuric acid.  The glycol exists as two geometric isomers which can be used to produce the corresponding geometric isomers of the tetrahydrofuran compound, or a mixture of isomers may be used, the isomers of the product being separated by fractional distillation.  The cyclisation may take place at temperatures above 70 DEG  C. and generally below 250 DEG  C.  Liquid diluents may be present, the heating being effected so that the diluent refluxes. A preferred procedure comprises reacting 1 : 2-dichlorobutene-3 with hydrogen peroxide in the presence of formic or acetic acid to produce 1 : 2-dichloro-3 : 4-epoxybutane or a mono ester of 1 : 3-dichloro-3 : 4-dihydroxybutane, converting the 1 : 2-dichloro-3 : 4-epoxybutane to 1 : 2-dichloro-3 : 4-dihydroxy-butane or to mono- or di-carboxylic acid esters thereof, and heating the glycol or esters under neutral or acid conditions to produce 3-chloro-4-hydroxytetrahydrofuran. Both geometric forms of the product are valuable solvents and by esterifying the free hydroxy group, e.g. with adipic acid to form the adipate, useful plasticizers for polymeric resins are obtained.

Title: Work feed mechanism for shoe stitchers
IPC: D05B15/04
Filed: 1933-06-17
Abstract: 409,149. Sewing - machines. ROWLEY, H. E. G., 9, Warwick Court, Gray's Inn, London.-(Landis Machine Co.; 201, Gano Avenue, St. Louis, Missouri, U.S.A.) June 17,1933, No. 17324. [Class 112.] In a McKay shoe stitcher, the presser foot is mounted independently of the work feeding member and is connected therewith so that raising the feed member raises the presser foot. A bushing 11 seated in the head 1 provides a bearing for the needle bar 7. A block 12 slides on the bushing 11 and has a lug 13 with an arm 14 to which is pivoted a carrier 16 for the feed point 17. A lug 18 on the carrier 16 engages a screw 19 on the arm 14 so providing an adjustable stop to limit the movement of the carrier. A spring 20 yielding- ly resists the movement of the carrier in the opposite direction. The arm 14, carrier 16 and feed point 17 are oscillated about a fulcrum by a horizontal link 22 connected to the lever 23, which is pivoted at 24 and oscillated by an adjustable arm 25 on the crank shaft 26. The other end has an arm 27 carrying a roller 28 riding a cam 29 on the driving shaft 6. When the operator depresses the treadle, the feed mechanism is lifted by the link 30 and the presser foot is lifted through the interengaging elements 36, 37. During stitching, the presser is lifted by a cam 38 which rotates a lever 39 having an arm 40 engaging a clamping dog 41 which tilts a nut to grip the threaded part of the presser in known manner. A lug 42 on the lever 39 seats a spring 43 which carries a rod 44 attached to a bell crank 45, the other end of which consists of a toe 46 fitting into a recess 47 in the block 12. Play between the arm 40 and dog 41 enables the block 12 to be locked before the presser bar is lifted. The pivot 13 remains stationary therefore throughout the oscillation of the feed point, which facilitates more even stitching than when the feed point is mounted on the presser bar. A spring 35 thrusts forward the end of a lever 32 to raise the block 12 through a link 30 till the face of the lug 36 engages the shoulder 37 on the presser bar. The height of the presser bar therefore, as determined by the thickness of the work, varies the amount of thread measured off.

Filed: 1936-06-25
Abstract: 476,446. Unwinding wire. BLASHILL, A. E. June 25, 1936, No. 17712. [Class 83 (iv)] [Also in Group IX] A non-rotating reel 1 for unwinding wire has inclined parts 1 on which the coils 2 are placed and oppositely inclined parts 6 from which the convolutions are led to a wire guide 10. The reel is supported by a shaft 3 carrying the wire 9 and by the coils of wire resting on a support 4. The guide which is triangular in form and has its apex coaxial with the shaft 3, is free to rotate and is provided with apertures 13, 16 for the wire. A hollow spigot 21 on the triangular guide 10 is mounted in a block 20 having a spherical surface surrounded by a similar surface of a clutch lever 18 pivoted at 23. Linkage 27 connects the lever with a counterweighted lever 28. Should the tension of the wire on withdrawal be excessive, the clutch lever 18 is operated to render the feed inoperative. A lever 25 is used to bring the clutch back to operative position. For handling heavy gauge wire a modified form of the apparatus is used with the guide 10 rotatable on a fixed shaft. In a further modification for small gauge wire, the trip lever is eliminated and the guide mounted on an arm carried by a slide attached to a weight. Specification 364,556 is referred to.

Title: Improved process for the manufacture of hydrocarbon substances from coal
IPC: C10B57/02
Filed: 1957-06-04
Abstract: A method for the conversion of coal and lignite into hydrocarbon substances including ethylene and benzene while obtaining a readilycombustible carbonized residue comprises retorting the coal or lignite while it is in a discrete particle form at a temperature between 450 DEG  and 600 DEG  C. and subsequently without intermediate condensation subjecting the evolved volatile materials to pyrolysis at a temperature between 750 DEG  C. and 1200 DEG  C. for a period of time between 0.2 and 2.0 seconds.  The volatile materials are normally cracked at a temperature between 750 DEG  and 950 DEG  C. but the production of acetylene may be augmented by cracking at about 1200 DEG  C.  Retorting may be by a batch process or by a continuous flash process, using rotating kilns, gravity or screw-fed retorts or by using a fluidized bed, in the presence of nitrogen, hydrogen, methane or steam.  In an example a cannel coal was retorted in a stainless steel tube at 550 DEG  C. and the evolved volatiles passed directly to an electrically-heated cracking zone heated to about 800 DEG  C.  From 500 grams of coal there were produced 286 grams of combustible char, 16.2 grams of heavy oil and tar, 116.9 grams of normally gaseous products and 39.2 grams of light oil.  The gaseous products comprised in grams, hydrogen 2.5, methane 42.2, ethylene 42.2, carbon dioxide 5.0, ethane 7.5, propylene 10.0, carbon dioxide 4.0 and C4 hydrocarbons 3.5. The light oil comprised in grams, benzene 9.2, toluene 3.8, xylene 1.2, styrene 1.0, naphthalene 3.5, methyl naphthalene 2.5.
